FURNACE FOR MELTING GLASS.

SPECIFICATION forming part of Letters Patent No. 434,184, dated August 12, 1890. Application led May 19,1890. Serial No. 352,418. (No model.)

as will enable others skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My present invention relates to improvements in floats or partition-screens for glassmelting furnaces; and it consists in certain novel features hereinafter described and claimed. l

In the annexed drawings, which fully illustrate my invention, Figure 1 is a plan View of the tank having my improved device in its operative position therein. Fig. 2 is a perspective view of the float or partition.

The tank A may be of any desired size or form, having the usual smoke-stack A', and is provided on the inner faces of its side walls withthe projections B B, as shown. The iioat C is constructed in two members having a combined length exceeding 'the width of the tank. The ends of the members are tapered somewhat, so that their outer ends will fit neatly -into the angles formed by the walls of the tank and the projections thereon, while their outer ends lit closely together. By this arrangement the members are prevented from moving away from each other and will be l even date herewith.

The construction of my improved float or partition is very simple, and its operation 5o and advantages will be readily understood. As the glass is removed from the front end of the tank, the glass left therein is caused to flow toward said front end, and consequently the impurities floating on the surface of the 5 5 glass arebrought against the ioat or partition and arrested by the same, so as to be prevented 'from being carried to the front end of the tank. It has been found that in practice some of the impurities would be carried 6o under the iioat and freed by the motion of the iiowing glass, and thus the object of the float or partition would be defeated to a certain degree. In my device such impurities as are carried under the float and freed will be permitted to rise ,through the vertical openings in the iioat and will be there held until volatilized and carried oif through the smokestack. Heretofore the iioat or partition has been constructed in one single body, and it 7o was found that in practice the motion of the flowing glass would cause the device to move from its position and lioat around in the tank, thus rendering it practically of no value. This objection is entirely overcome by the use of my device, as the iioat is constructed in two members having a combined length greater than the width of the tank, and consequently the motion of the iiowing glass will serve only to hold the float more firmly in its 8o position.

My ldevice is very simple in its construction, and its advantages are thought to be obvious from the foregoing description, taken in connection with the accompanying drawings.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

l. The combination, with the tank, of the floating partition composed of two members 9o having a combined length exceeding the width of the tank, and having their -inner ends bearing against each other and their outer ends bearing against the walls of the tank, substantially as set forth.

2. A floating partition or screen for glassmelting furnaces provided with vertical openings, substantially as and for the purposes set forth.

3. The combination, with the tank having inwardly-extending projections on its side Walls, of the loating partition consisting of two members having their inner ends bearing against each other and their outer ends resting in theI angles formed by the projections and the walls of the tank, the combined length Io of said members exceeding the width of the tank, substantially as described.

In testimony whereof I hereunto affix my signature in the presence of two witnesses. LUKE HOUZE. Witnesses:
